This invention relates to atool for setting anchors.` f y It is well known thatscrew anchors are used for obtaining anchorage in walls of brick, stone, or cementitious material not adapted: to direct-ly receive a threaded velement orbolta, he y n y One type lof anchor `which is used for this lpurpose comprises an expansion`v member of relativelysoft metalmounted on an expanding member of relatively hard metal. In

order to expand or setv the anchor, the soft metal memben or sleeve is tamped on the hard metal member and is forced outwardly into firm gripping engagement with the wall opening. y For an illustration of this type of anchor see Patent No.;1,161903 to Ackerman et al., granted December 21,1915.

* z When thehole for receivingthe anchor is .drilled in a wall or Vother structure, yconsiderable dust accumulates at thefinner end of the hole and when the anchor is placed therein this dust tends to enter the inner end of the longitudinalopening in the anchor.' This l Y whichthe tool is utilized;

dustimpedes the travel of the bolt or threaded member that is inserted in the anchor after the anchor has beenexpanded. A v y kThis invention has for its salientfobjec'tto providela setting tool for an anchor of. the type specified so Vconstructed that it will pref vent dustfrom entering. the threaded opening in the anchor when the kanchor is positioned in y a `Wall opening 'and expandedA therein. e

Further .objects of the invention will appearfrom the following specification taken in connection with the drawings, which form a partof thisapplication, and `in which Fig. 1 is a longitudinal sectional elevation of one form of anchor in connection with Figs. 2 and 3 are end elevations ofthe two ends ofthe anchor shownin Fig. 1

The (invention briefly described consists of a vtool for use with anchorsof the type speciviedandvcomprising a body portion which is adapted to engage the expansionk member of the vanchor and a pilot Orishank slidably carried byl the tool andso dimensioned withrefl erence to the lanchor that it will extend into thel inner portion Vof, the longitudinal. or threaded opening in the anchor. This pilot acts asa guide for the body portion when the body portion is driven against the expansion member and also functions to prevent the dustL accumulated at the end of the hole from: enter"-I ing the inner end of the longitudinal opening in the anchor and thereafter impeding'the passage of the threaded element, such as abolt in'thethreaded'opening in'the'anchor. A

the following description. Y

",Figs. 1, 2 and 3 illusrateone form of anchor particularly adapted for expansion .by the tool. This anchor comprises an inner expanding member20 having an inner por-v tion 21 provided with a tapered outer surf;

face 22. The expansion member 20 is preferably formed of relatively hard metal and has va longitudinal -opening therethrough, a portion 23 of the opening being threaded and the remaining portion 24 beingsubstantially cylindrical. A expansible member 25, preferably formed of relatively soft metal, is mounted on thefoutersurface yof the member 2O and has an-k opening formed therethrough. In the form ofthe invention shofwn inFigs. lto 3,'

' Fig. 4 illustrates a slightly different form of anchorV in'which the opening 50 at the inner end of the expansion member 2O is flared. This flared opening Vdoes permit a small quantity of the dust at the inner end of the hole 4l to enter the flared opening 50.

Fig'. l1 illustrates a'slightlyA different form of tool in which the'pilot `55 is threaded' as shown `at 56 for a portion of its length; .The

'of the tool, and arpinGO extendsthrough the vhead `58` of thepilot and into Vslots 6l formed in the opening 59.` The *pilot is, therefore, 5b longitudinallyslidable in the openingVV 59 but is non-rotatable therein. The'type of tool just described and shown F l1 is' particularly adapted for posi-v tioningfanchors a predetermined depth in the bo1e4l in vthe Wall `or supporting structure. In order to' accomplish this.l the pilot is threadedthrough the anchor a desired distance andthe anchor and pilot are then placed in .the 'hole.f *Thedistance from` the innerV end of thejpilot to the inner end of the anchor will determine the distance from the` bottom of the hole or inner;` end 4l tothe. anchor. l/Vhen the anchor has'fbeen" `.so positioned, force is exerted ontheouter. end of the body portion 30l of the tool' and the'l expansible portion ofthe anchor is forced inwardly. and laterally Vinto iirm` gripping engagement; with the wall: opening 41. It will `be evident that this form of tool can be used with the anchor of Figs. 1, 2 and 3, Wthlike results. Fromlthe foregoing specilicationiit will be iio , evidentthat a simple and practical tool for talnpingV or. setting anchors Yhas been provided and thatthe use of this tool will ef-` fectively iprevent dustfrojm entering the Y anchorandV thereafter impeding thepassage cfa bolt or threaded elementthrough the anchor.
